Advanced Tab Field Descriptions

Configure the following parameters:

Routing	Determines the routing mode (RIP, Routing Information Protocol) used on the
	PPP interface.This is the same function as the Framed-Routingattribute for
	RADIUS authenticated users.
	Data Options
	z None—Disables RIP over the PPP interface.
	z Send—Sends RIP over the PPP interface.
	z Listen—Listens for RIP over the PPP interface.
	z Send and Listen—Sends RIP and listens for RIP over the PPP interface.
	Default: None
ACCM	Specifies the ACCM (Asynchronous Control Character Map) characters that
	should be escaped from the data stream.
	Field Format: This is entered as a 32-bit hexadecimal number with each bit
	specifying whether or not the corresponding character should be escaped. The
	bits are specified as the most significant bit first and are numbered 31-0. Thus
	if bit 17 is set, the 17th character should be escaped, that is, 0x11 (XON). The
	value 000a0000 will cause the control characters 0x11 (XON) and 0x13
	(XOFF) to be escaped on the link, thus allowing the use of XON/XOFF
	(software) flow control. If you have selected Soft Flow Control on the Serial
	Port, you must enter a value of at least 000a0000 for the ACCM.
	Default: 00000000, which means no characters will be escaped
MRU	The Maximum Receive Unit (MRU) parameter specifies the maximum size of
	PPP packets that the IOLAN’s port will accept. If your user is authenticated by
	the IOLAN, the MRU value will be overridden if you have set a MTU value for
	the user. If your user is authenticated by RADIUS and the RADIUS parameter
	Framed-MTUis set in the RADIUS file, the IOLAN will use the value in the
	RADIUS file in preference to the value configured here.
	Range: 64-1500 bytes
	Default: 1500
